Xiaomi SU7 High-Performance Brake Kit Features, Functions and Safety Precautions

TapTechNews September 20th news, Xiaomi Motors officials发文 tonight, giving a detailed interpretation of the newly launched "High-Performance Brake Kit".

TapTechNews summary as follows:

1. "Do I have to upgrade the High-Performance Brake Kit?"

No need to upgrade обязательно.

The High-Performance Brake Kit is specially designed for performance enthusiasts who pursue intense driving. For users who only need daily driving needs, the original brake system of Xiaomi SU7 can easily handle it without additional upgrade.

At present, the upgrade service of the High-Performance Brake Kit has been launched, and the expected cost is $590, and users in need can make an appointment in advance by calling 400-182-6888. At the same time, we strongly do not recommend that ordinary users easily attempt intense driving. If you need to try, please first understand the product performance boundaries, master professional driving knowledge, and choose a professional site or track before attempting the challenge.

2. High-Performance Brake Kit designed for performance enthusiasts

The High-Performance Brake Kit is specially designed for performance enthusiasts who pursue intense driving. For users who want to try intense driving, they need to upgrade the corresponding accessories first, do not rashly challenge the extreme track conditions in the original state of the vehicle.

The kit includes high-performance brake pads (front/rear) and high-boiling-point brake fluid. Among them, the high-performance brake pads adopt a low-metal formula. Compared with the NAO (non-asbestos organic) formula of the original brake pads, the maximum friction coefficient is increased to 0.45, and the optimum working temperature can reach up to 400°C, and the anti-thermal recession ability is stronger. The dry boiling point of the high-boiling-point brake fluid can reach 320°C through the adjustment of the formula, making it more suitable for more intense driving conditions.

But after upgrading the High-Performance Brake Kit, there are 4 points that everyone should pay attention to:

The addition of a small amount of metal raw materials in the formula of high-performance brake pads may occasionally cause a metallic howling sound during braking, which is a normal phenomenon.

After replacing the high-performance brake set, the braking force and braking feel will change, so everyone should be careful when driving.

The high-performance brake pads need to be run in for hundreds of kilometers before reaching the best working performance. It is recommended that after replacing the brake pads, do not immediately conduct intense driving to prevent danger.

The components contained in the high-performance brake set are all consumables, and the replacement cycle will change according to the driver's driving habits and usage environment. After intense driving, please check the state of the braking system in time to prevent the safety risk caused by excessive wear of the components.

3. New "Energy Recovery Enhancement" function, with a maximum deceleration of 0.36g

Xiaomi SU7 OTA1.3.0 has added a new "Energy Recovery Enhancement" function, which can better meet the performance enthusiasts who pursue intense driving when combined with the High-Performance Brake Kit.

This function can be manually turned on in the "Master Mode" App on the vehicle central control screen. After the function is turned on, it can still maintain kinetic en ergy recovery when the vehicle is in emergency braking or the anti-lock braking system (ABS) is working, and contribute a maximum deceleration of 0.2g. And when the ABS is not triggered, the maximum deceleration of the braking energy recovery system can even reach 0.36g, which can significantly improve the vehicle's anti-thermal recession ability on the premise of ensuring braking stability, which also benefits from the world's first Bosch DPB+ESP10.0 intelligent braking system of Xiaomi SU7.

It should be noted that the "Energy Recovery Enhancement" function needs to maximize the use of the tire's grip, so the function is only used in a closed site and when the road surface is dry. Turning on this function on a wet and slippery road surface may cause the wheel to lock and skid, presenting a safety risk.

4. The original braking system can better meet daily driving needs

The original braking system of Xiaomi SU7 can bring a better and more comfortable daily driving experience, so for users who only need daily driving, there is no need to upgrade the High-Performance Brake Kit.

The High-Performance Brake Kit supports a higher working temperature and can effectively enhance the braking force and feel, but there will also be disadvantages such as increased noise, increased dust, weakened comfort, and changed braking feel. And the original braking system can not only bring a better silent effect and comfortable experience, but its braking performance and durability can fully meet the needs of daily driving.

Xiaomi SU7 Max is not only equipped with a set of Brembo high-performance four-piston fixed brake calipers and perforated brake discs, but also uses the brake pads of the NAO (non-asbestos organic) formula, which has been specially optimized for the noise, dust and braking feel of daily driving to bring better braking performance and comfortable experience. At the same time, the effective friction area of the front brake pads is larger than that of the same-level sports car of the luxury first-line brand, and the braking distance from 100km/h to 0 can be as low as 33.3m.

In addition, all models of Xiaomi SU7 are standard with the world's first Bosch DPB+ESP10.0 intelligent braking system, realizing the decoupling design between the braking pedal and the braking actuator, bringing a faster and more stable operating feel and making driving more reassuring. To fully ensure safety, the braking system of Xiaomi SU7 also adopts a "quadruple braking redundancy" strategy:

If the braking pedal is stuck, braking deceleration can be achieved by long-pressing the P gear;

If a single braking module fails, DPB can serve as a backup with ESP and provide almost the same braking force and pressure-building speed;

If DPB and ESP fail at the same time, effective deceleration can still be achieved by relying on traditional mechanical hydraulic braking;

We also have the last guarantee, through the kinetic energy recovery function of the Xiaomi super motor, the deceleration can reach up to 0.36g with reverse torque, and still can brake quickly.

Xiaomi Motors officials finally remind: Xiaomi SU7 is a high-performance luxury technology sedan built for urban scenarios. Before conducting the most stringent and most e xtreme track conditions, the vehicle must be reconditioned. Do not rashly challenge the extreme track conditions in the original state of the vehicle to ensure the safety of people and cars.
